He mea pono loa ka ʻenehana hana hydrogen ʻōmaʻomaʻo no ka hoʻokō hope ʻana o kahi hoʻokele waiwai hydrogen no ka mea, ʻaʻole like me ka hydrogen hina, ʻaʻole hana ka hydrogen ʻōmaʻomaʻo i ka nui o ke kalapona dioxide i ka wā o kāna hana ʻana. ʻO nā cell electrolytic oxide paʻa (SOEC), e hoʻohana ana i ka ikehu hou e unuhi i ka hydrogen mai ka wai, ke huki nei i ka manaʻo no ka mea ʻaʻole lākou e hana i nā mea haumia. Ma waena o kēia mau ʻenehana, loaʻa i nā cell electrolytic oxide paʻa wela kiʻekiʻe nā pono o ka pono kiʻekiʻe a me ka wikiwiki o ka hana ʻana.
ʻO ka pākahiko proton ceramic kahi ʻenehana SOEC wela kiʻekiʻe e hoʻohana ana i kahi electrolyte proton ceramic e hoʻoili i nā ion hydrogen i loko o kahi mea. Hoʻohana pū kēia mau pākahiko i kahi ʻenehana e hoʻemi ana i nā mahana hana mai 700 ° C a ʻoi aku paha a i 500 ° C a i ʻole haʻahaʻa, no laila e hōʻemi ana i ka nui o ka ʻōnaehana a me ke kumukūʻai, a hoʻomaikaʻi i ka hilinaʻi lōʻihi ma ka hoʻopaneʻe ʻana i ka ʻelemakule. Eia nō naʻe, ʻoiai ʻaʻole i wehewehe pono ʻia ke ʻano hana koʻikoʻi no ka sintering protic ceramic electrolytes ma nā mahana haʻahaʻa i ka wā o ke kaʻina hana hana pākahiko, he paʻakikī ke neʻe i ke kahua kūʻai.
Ua hoʻolaha ka hui noiʻi ma ke Kikowaena Noiʻi Materials Energy ma ka Korea Institute of Science and Technology ua ʻike lākou i kēia ʻano hana sintering electrolyte, e hoʻāla ana i ka hiki ke kūʻai aku: he hanauna hou ia o nā pila keramika kiʻekiʻe-kūpono i ʻike ʻole ʻia ma mua.
Ua hoʻolālā a hoʻokō ka hui noiʻi i nā hoʻokolohua hoʻohālike like ʻole e pili ana i ka hopena o ka pae transient ma ka electrolyte densification i ka wā o ka electrode sintering. Ua ʻike lākou no ka manawa mua e hiki i ka hāʻawi ʻana i kahi liʻiliʻi o ka mea kōkua sintering gaseous mai ka electrolyte transient ke hoʻolaha i ka sintering o ka electrolyte. He mea kakaikahi a paʻakikī ke nānā ʻia nā mea kōkua sintering gas. No laila, ʻaʻole i hāpai ʻia ka kuhiakau e hoʻokumu ʻia ka electrolyte densification i loko o nā cell proton ceramic e ka vaporizing sintering agent. Ua hoʻohana ka hui noiʻi i ka ʻepekema computational e hōʻoia i ka gaseous sintering a ua hōʻoia ʻaʻole e hoʻopilikia ka hopena i nā waiwai uila kū hoʻokahi o ka electrolyte. No laila, hiki ke hoʻolālā i ke kaʻina hana hana kumu o ka pākaukau proton ceramic.
"Me kēia haʻawina, hoʻokahi ʻanuʻu mākou e kokoke aku ai i ka hoʻomohala ʻana i ke kaʻina hana hana koʻikoʻi no nā pila proton ceramic," wahi a nā mea noiʻi. Hoʻolālā mākou e aʻo i ke kaʻina hana hana o nā pila proton ceramic nui a kiʻekiʻe i ka wā e hiki mai ana."
